What main idea about the nature of the cell did historical scientists disagree on?
VLD [36.1K]

Explanation:

Scientists didnt belive that there are cells untill robert hooke (1665). He observed the cells in a cork slice with the help of a PRIMITIVE microscope

Leeuwenhoek (1674), with the help of an improved microscope, discovered free living cells in pound water for the first time.

It was robert brown in (1831) who discovered the nucleus in the cell.

Purkinjie in 1839 coined the term 'protoplasm' for the fluid substance of the cell.

THE CELL THEORY, that all plants and animals are composed of cells and that the cell is the basic unit of life, was presented by two biologists, schleiden (1838) and schwann(1839). The cell theory was fuether expanded by virchow (1855) by suggesting that all cells aris form PRE-EXISTING cells. With the discovery of the electron microscope in 1940,it was possible to observe and understand the complex structure of the cell and its various organelles.

Well, thats the history of the discovery of cells.

What feature is used by both the respiratory and digestive systems?
Aleksandr [31]
The digestive and respiratory tracts include the pharynx. The pharynx is found at the back part of the throat and is connected to the mouth and the nasal cavity. It then extends to connect into the esophagus and larynx. The pharynx serves as passageway for air during respiration and food for digestion.

a man with hemophilia, which is a sex-linked recessive disease, lives a full life through modern medicine. he eventually marries
GarryVolchara [31]

All of his offspring will be free of the disease, assuming his wife is not a carrier.

The phenotype of an organism is a collection of its observable traits or characteristics. The term describes the physical form and structure of an organism as well as its physiological and biochemical traits, behavior, and results of that behavior. The blood clots incorrectly as a result of hemophilia, a genetic bleeding disorder. Both spontaneous bleeding and bleeding after an injury or surgery may result from this. Numerous clotting proteins found in blood can help to stop bleeding. Blood clotting is impaired by a rare disorder called hemophilia. It happens as a result of the body not producing enough of a protein called a clotting factor. Clotting aids in stopping the bleeding after an injury or accident. In the absence of coagulation, bleeding may be excessively simple or prolonged. There is currently no known cure for hemophilia, despite the fact that treatment for those with the condition has significantly improved over the past few decades.

Match the following. 1. period during the life of a cell when it has finished mitotic division G1 phase 2. period during the lif
zimovet [89]

Ans.

The cell cycle includes a series of events that results in the formation of daughter cells from a single parent cell. These events include interphase, followed by M phase. The interphase consists of three phases, G0 (Gap 0) phase, G1 phase, S (synthesis) phase, G2 phase, while the M phase consists two phases, karyokinesis (mitotic or meiotic phase) and cytokinesis. At the end of cell cycle, cell enters into G0 phase again and the cycle goes subsequently.

The sequesnce of cell cycle events can be written as follows:

G0→G1→S→G2→M→G0→G1→....

Thus, according to the cell cycle sequence, these terms can be matched as:

1. When a cell finishes its mitotic division, it enters to G0 phase, which is also known as rest phase. Thus, statement 1. matches with G0 phase.

2. The period between end of mitosis and synthesis of genetic material for next mitotic division shows G1 phase, in which cell prepares itself for division. Thus, statement 2. matches with G1 phase.

3. The period of interphase between synthesis of new genetic material and the beginning of mitosis is G2. Thus, statement 3. matches with G2 phase.

4. The period between two mitotic division is interphase. Thus, statement 4. matches with interphase.

5. The period of cell division, during which a cell is performing actual cell division is M phase. Thus, statement 5. matches with M phase.

6. The period of interphase, during which genetic material gets doubled is synthesis or S phase. Thus, statement 6. matches with S phase.
